Referring particularly to Fig. l, it is seen that the invention may beapplied to a, pair of corn harvester husking rolls rotatably supportedin coacting side-by-side relation by longitudinally spaced front andrear pairs of bearing structures I and 2, respectively, and that eachroll may include an inner shaft member 3 to which is removably secured aforward ear-snapping section 4, an intermediate trash-removing section6, a rear husk-removing section 1, and a rear trash-removing part 8. Therear end portions of the inner shaft members 3 are drivingly connectedby rneshed gears 9 and the end of one shaft member is provided with asuitable coupling II for connecting same with a power shaft or source(not shown). In this connection, a pair of rolls such as hereindescribed is adapted to be utilized in a corn harvester of the typedisclosed in U. S. patent, C. J. Scranton, 2,340,084, to which referencemay be had for additional information as tothe general arrangement andcoaction of parts.

The rear end of each trash section 6 terminates in a cylindrical portionI2 of reduced diameter provided with a pair of longitudinally extending,diametrically opposed grooves, keyways, splines or the like I3 (seeFigs. 2 and 3), and the forward end of rear trash section 8 alsoterminates in a cylindrical portion I4 of reduced diameter provided withlongitudinally extending grooves, keyways, splines or the like I6similar in shape, num.- ber and arrangement to the grooves I3 in theopposed reduced end portion of trash section 6. The trash sections 6 and8 are secured to the inner shaft member 3 with their grooves I3 and I6disposed in substantial longitudinal alinement.

In this embodiment of the invention, the husking section 'I comprisesfront and rear parts (the rear portion of trash section 6 and the frontportion of trash section 8, respectively), a relatively thin tube IIsurrounding the portion of shaft member 3 included between trashsections 6 and 8 and having its opposite end portions telescopinglysurrounding and radially rigidly supported by the cylindricalend-portions of the front and rear parts, and a pair of internalprojections, keys, or the like I8, which may be riveted or otherwisesecured to or formed on each end of the tube, are slidably disposed inthe diametrically opposed grooves I3k and I6 of the front and rearparts, i. e., the rear and front portions I2 and I4 of trash sections 6and 8, respectively. And it should now be obvious that the connectionbetween the ends of the tube and the front and rear supporting parts orelements prevents an angular movement of the tube relative to such partsand permits the ends of the tube to move longitudinally relative to theparts supporting same as the tube flexes laterally relative to itslongitudinal axis. Moreover, if the tube should become worn or damagedsuiciently to warrant replacing same, only the tube part need bereplaced, and all that has to be done, in order to remove the tube partfrom the shaft member, is to remove only those other parts which arese'- cured on the shaft member outwardly of either the front or reartube supporting part, and to then remove the appropriate tube supportingpart and slide the tube longitudinally of the shaft member.

Referring also to Figs. 4 and 5, it is seen that one of the tubes lscovered with a relatively thick layer of rubber I9 and is formed ofseparable, interchangeable arcuate sections 2l having outwardly flangedlongitudinal edges or edge portions 22 detachably united in abuttingrelation by means of bolts or the like 23. The bolts may be readilyinserted and removed through alined, flange exposing holes or recesses24 formed in the lay-er of rubber I9 which is preferably of a thicknessapproximately equal to the width ci the flanged portions 22. The othertube section is of nonsectional, uncovered construction and is providedwith a longitudinal series of pairs of opposed holes 26 and with springhusking pegs 2'I which project through the holes 2E and are held inplace by rubber plug-like members 23 operative to permit the pegs torecede within the holes 25 when engaged by the surface of the opposedroll. The construction and mounting of the husking pegs forms no part ofthis invention and if more detailed information is desired concerningthis feature, reference may be had to the disclosure of C. J. ScrantonsPatent Number 2,391,846, led November 6, 1943.

The ends of the sectional tube are supported on and connected with thecylindrical end portions of the front and rear tube-supporting parts inexactly the same manner as the uncovered roll, i. e., as hereinbeforedescribed, the only difference being in the external diameter of thecylindrical portions of the front and rear tubesupporting parts which inthis case differ an amount nearly equal to twice the thickness of therubber layer I9 as is evident from a consideration of Fig. 4. And itshould now also be obvious that in addition to preventing anoverstressing of the connections between the ends of the tubes and theparts supporting same, the connections just referred to permit one ormore of the rubber covered tube sections to be readily removed withoutdisturbing the front and rear tube-supporting parts or any other partsof the roll assembly, simply by removing the readily accessible bolts23.

Referring now to the modified construction shown in Figs. 6 and '7 inwhich like numerals are used to designate the same or correspondingparts, it is seen that the ends of tube I1 may be connected with frontand rear parts or elements secured to shaft member 3 for rotationtherewith by providing the plane annular end surface of each of suchparts (the connections between the front and rear parts are identicaland therefore only the connection between the front part, trash section6, is shown) with a pair of vdiametrically alined slots 29, and byproviding each end of tube I'I with a radially flanged annular plugmember 3i having an exterior end surface which is coextensive with andabuts the end surface of the opposed section or part and which presentsa pair of diametrically alined projections or ribs 32 slidably disposedwithin the slots 29. The plug members 3I may be inserted in the en ds ofan integral tube and secured therein by a pressed fit or otherwise toprevent an angular movement of the tube relative to the plug members,and if seguace? g5 :the tubesisformedffnfi:separablev'sectionsaasilindicated in Figs. 2, 4 and 5, theendsibf--theisec tions .should be; clamped:l aroundtheip'lugsnby the.actionfofbolts .unitn-sufficient lforce'ltot prevent .af relative`angular@movemenimnfxthe tube :and J plugs eitherv with tore-Withoutthexaid Y:of interen- 'gaged projections inotfshown) .-.-Bothf fofrthe':constructionsr herein". shownand .described aiiord. a relativelyfinexpensilve,.I rugged 'shaftfmemberceuclosect thereby; means mounting--saiditubein spacdzsconcentricr:relationifwithf refspect. to..saidportion. vof..1the-lslf1aft member `comeprisingtvannular;,plug .membersmounted on'l said :shaftim'ember :for movement; axially thereofl andaffordinga radially rigid support for-the opposite :endszofxlsaidtube,.;.said: plugmembers 1 and? lthe opposed ends of saidparts having portions Ytliere- -of::nonrotatably :detachably engaged:forf relative .constructionin that. no fpartmffthehusking .roll 10eaxialzzmovement sonas to permitrthe ends-0f. said f. assembly isAsecured to shaftmemben 3sat alpoint remote from .the -rear'bearingstructure therefor .byy a 1connection requiring. a hole,ikeyway.or,other:opening in or.Y through Itl'1efslf1aft,Whichwveakens -ltuberto move:longitudinally `relative 'to said' parts .andiishaftt-:memberasthenltube" flexes :laterally vrelative to "its longitudinal axis said?ftube lbeing .formedzofr complementary rubber `covered arcuate zsame,and .inlthatrthe .-endsfofl tlle--tu-bel parts-,of ':15 ...s-gctions;havngyoutwaymy aangeda:longitudinm t-he' husking Vroll are:substantially .tree to'.A move longitudinallyr relative; vto 'witherfrontrffand frear shaft,-.carriedy tube-supp orting rparts vas lthe.tubes Viiex` .laterally rrelativettotheir longitudina1..axes.
